本文报导了氯氰菊酯在桃子上的残留动态试验。试验点分别设在北京及临安两地。试验结果表明,在桃子结果期按常用浓度25-50ppm喷施,最多喷三次,最后一次喷药距采收期15天分析全果残留量均未超过规定的最大残留限度2ppm。如将果皮及果肉分开检测,则皮中能检出,果肉未检出,故对桃子果肉食用是较为安全的。 This paper reports the residual dynamic test of cypermethrin on peaches. Test points were located in Beijing and Lin’an two places. The test results showed that the peach fruit at the usual concentration of 25-50ppm spraying the results, the maximum spray three times the last spray 15 days from the harvest of the analysis of the whole fruit residues did not exceed the required maximum residue limit of 2ppm. If the peel and flesh were tested separately, then the skin can be detected, the flesh was not detected, so peach pulp consumption is more secure.
